I'd like to know whether anyone has tried Gastrodia, and what results they had. I've just ordered some. The link below is a review of scientific evidence for some biological activities of Gastrodia, which is well known in TCM. (Incidentally, they don't mention its anti-viral properties.) It's called Gastrodiae Rhizoma in the article, which is simply Latin for rhizome of Gastrodia. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3942998/ The scientific evidence sections are: Anticonvulsion Antioxidation Treatment for Mental Disorder Neuroprotection Memory Improvement Anti-cardio-cerebral Anti-inflammation and then a separate section on Anti-depressant mechanisms On the TCM websites, they always mention that it is used to treat "neurasthenia".
